Trivia

In a Pokémon card related to Koga, called Koga's Ninja Trick, there is a symbol that looks similar to a swastika. However, it is actually totally different, in positioning and in meaning. A Swastika is in a diamond angle, and the points on it point clockwise; the symbol depicted on the card was in a square angle, and the points were counter clockwise. The symbol on the card was of a different culture and was many years before the Nazi Party, and meant "peace". When the card was released in the U.S., it was changed to a different symbol.
